R. 0. WHITE REFRIGERATING DEVICE Filed Nov. 2, 1929 2 Sheets-Sheet 2 Patented Jan. 12, 1932 PATENT OFFICE ROBERT 0. WHITE, OF LOS ANGELES, CALIFORNIA anrnrenna'rme Davies Application filed November 2, 1929. Serial No. 404,450.

This invention relates to a multiple fluid cooler particularly adaptable toinclude a single main refrigerant control unit. In M cooling chambers assemblies used for several liquids such as beverages various cabinets in common practice have heretofore been used in which a bath cooled by a refrigerant has had'immersed therein several beverage containers constituting partsof flow line for beverages, a separate beverage flowing through each beverage coil or container. Chambers for the cooling'of bottles or articles are also provided. This constitutes My an indirect method and means for cooling the beverages and is commonly used in soda fountains. Another practice has been to-place Within the fluid cooling chambers, refrigerant vaporizing pipes or chambers, there being'arefrigerant vaporizin chamber for each fluid coolingchamber. uch fluid cooling chambers thushave been cooled from the inside. The'present invention has for an object the provision of an assembly including a fluid it the outside of the assembly and function as a cooling medium for a storage cooler such as is used in soda fountains in common practice for bottles or other articles. Another object of this invention is to provide details of structure wherein any or all of the following featuresare included in the assembly: a liquid inlethaving openings to direct the liquid to be cooled against'an ice body therein or the section of wall of the chamber transfer-ring heat between the vaporizing chamber and the fluid cooling chamber; aliquid outletto take liquid from the chamber adjacent such ice b'ody or heat transfer wall; inlet openings, outlet openings, or both having their openings disposed at different distances "cooling chamber and a vaporizing chamber so that a growing ice body may close all but one inlet and outlet opening before shutting off the flow of liquid; the inlet and outlet openings being of varying cross sectional areas and disposed totake and discharge liquid from'largest openings nearest the ice body or heat transfer section of wall; and outside controlled heat insulated walls movable to shield the heat transfer section of wall of the fluid cooling chambers or to expose the latter to meet the demands of individual needs.

.These'objects together with other objects and corresponding accomplishments are ob-' tained by meansofthe embodiments of my invention illustrated in the accompanying drawings, in which:

Fig. l is a plan view-of an assembly whereinthere is a single refrigerant control unit and vaporizing chamber, four liquid cooling chambers, and an air cooling space; Fig. 2 is a section as seen on the line 2-2 of Fig. 1; Fig. 8 is a section as seen on the line 3-3 of Fig. 2 showing a fragment of the vaporizing chamber and a liquid cooling chamber; Fig. 4 is an enlarged detail view as seen on the line 4-it of Fig. 3; Fig. 5 is a vertical section through an assembly having a single vaporizing chamber and two liquid cooling chambers; Fig. 6 is a section as seen on the line '66 of Fig. 5; Fig. 7 is a perspective view on an enlarged scale showing another form ofinlet, the outlet being substantially identical; and F ig. 8 is a perspective View showing the heat insulated shield.

Referring more particularly to Figs. 1 to 4 inclusive, the vaporizing chamber is marked 10 and consists of'a-tank having extensions 10a and 10-'b closed by a head 11 at one end and a head 12 at the other end upon whichare mounted refrigerant control valves 13, these being of a form well known in the art. Disposed alongside and without the vaporizing chamber 10 are liquid cooling chambers 14.

As illustrated herein, the liquid cooling chambers are four in number and are cylindrical, being of less length than the vaporizing chamber 10. However, the exact length of the liquid cooling chambers in relation to the length of the vaporizing chamber is not pertinent to the present invention. Walls together with portions of the fluid cooling chamber walls 14 and the extensions 10-a and 10Z) define a vaporizing chamber. Heat is transferred from the liquid cooling chambers 14.- to the vaporizing chamber. The sections of walls of the liquid cooling chambers which form a portion'of the Walls of the vaporizing chamber constitute heat transfer sections. Mounted adjacent each heat transfer section is an adjustable heat'insulated shield 16 later described. Each liquid cooling chamber is adapted to be operated. independently'so that several draught beverages may bepassed therethrough. They may also be connected in series so that any. two may operate as a multiple stage cooler. In such instance by-passes should be provided in order that liquid may be passed around any cooling chamber which may become inoperative. Anice body may buildup on the heat transfer section of the wall of'a liquid cool ing chamber as indicated by X-in Fig. 2. As

the liquid cooling chambers are of like con-- struction, onlyone will be described. Leadinginto one end of a chamberlt is an inlet pipe 17. On the inside of chamber 14 and projecting laterally therefrom are three pipe sections 18 a, 18 b, and18'c, of different lengths and constituting an inlet designated generally by 18; The short inlet section 18a is of less cross-sectional area than 18 6, aridlS- -b is less than 18f0 as best shown in Fig.4. Liquidentering the chamber, providing the end of section 18- 0 is open will follow the path of'least resistance and the" largeproportion will pass through section 1-80, being directed against, the ice body X. If the ice body should build up so as to close the end of the section 18.c,then liquid will bedelivered through section 18b ingreater amount than through section 180.

If-both sections 18o and 18-b are closed by 1 the ice body, then liquid will be delivered through section 18a. Thus, liquid is delivered close to and against'either thejice body-or the heat transfer wall section to operate withthe best thermal efliciency. The outlet indicated generally by '19 consists of pipe sections 19-a and 19'Z and 190 which operate to take the liquid from chamber 14 adjacent the heat transfer wall or the ice body, the largest discharge openings being closest tofthe ice body or heat transfer section of Wall. p I i i 7 Referring more particularly toFigs. 5 to 8 inclusive, avaporizing chamber is marked 1 2O andtwoliquid cooling chambers 21. A

wall-22 forthe vaporizing chamber has fins 23thereon. The delivery and discharge pipes for the liquid chambers are shown as entering one end ofthe liquid cooling chamber. The inlet pipe 24 is single and'disposejd along the lengththereofare openings 24b, 24-c, and 24+d.. The opening at the *end marked 24.a is of larger cross-section than opening 24b, opening 240 being less than 24-Z and opening 24-(Z being the smallest. The

operation of the inlet pipe will be obvious.

Delivery pipe 25 is of similar construction. I

Insulating shields 26 correspond to heat insulating shields 16 shown in Figs. 1 to 4. These shields are formed of any suitable material and are of such curvature that it may 11s against the outer surface of the corresponding liquid cooling chamber forming a portion of the vaporizing chamber wall. A shaft 27 is formed thereon and journalled in the end walls so that a shield may be swung to and from its liquid cooling chamber wall. One end of the shaft is shown extended to the outer side and provided with a handle 27 for manipulating the shield. When the shields lie against their chambers, the heat conductively is less, and less heat will be transferred from a cooling chamber. Although the shields are shown arranged for manual operation, they may be operated automatically by any. suitable means.

Itwill be noted that in both forms. of the invention, air may be passed around the outside of the assembly and thus cooled. The
